A signal generator of a device usually found in laboratories where electronics practices are performed; its primary function is to produce periodic or non-periodic signals to use these signals to perform tests, designs, or repairs in electronic systems. This instrument should not be confused with an oscilloscope, which will be discussed in the next topic.
As the technology advances, so do the tools to test such technology, in the case signal generators were not always so practical since only a decade ago, they were considered in functional devices due to their wide range of limitations. However, this has changed over the years to the point that there is already a first signal generator for each job. They have evolved so much that some of these generators now allow a direct connection to a computer, which adds many applications, such as registering each signal produced and that of programming the Generator so that it emits a wide range of signals in a specific sequence, of course, the more functions one of these Generators has, the higher the cost will be.
Operation of Signal Generators
A signal generator is a handy tool if used correctly, the specific function of a generator is to create a particular type of wave such as sine waves, triangular, square, and sawtooth. What characterizes the generator is that you can configure each signal so that the frequency varies from less than one hertz to several kilohertz.
Another proof the Signal Generators is that you can use different outputs of the generator to produce a mixed signal, for example, if you need a square wave to determine the linearity of an audio system, this can be done and apart you can use a different output for another type of signal to test another part of the system.
Operation of a signal generator
For this section we bring you a video in which you can see how a signal generator is operated, we bring you a video because it shows you more practically and interactively what you can do with this laboratory tool.
